That is true, but my current rent just says "No more than two of the same species of pet" so you can't have 5 dogs or 100 gerbils, etc. I technically go over with "fish" but it's not like they will know. Knowing about 5 dogs is much more obvious.

I will definitely keep the 20 Gal in mind. So far my friend is having success in her 5 gal...maybe I can ask if any of my friends have an extra tank I can borrow for now >_<, then get a divider later

Unfortunately 2 neons died in the process but all 9 remaining ones from the original 12 have found a nice home X_X...we both ended up giving both our schools of neons to my aunt who has a 20 G for them. She was kind of upset at us but oh well X_______X
